To all whom it may concern: l

. Be it known thatwe, CLARENCE H. How- ARD and'CHARLEs T. WEs'rLAKE, citizens of the United States, residing at St. Louis, in

the State of Missouri, have invented a newand useful Improvement in Car-Underi'rames,

of which the following is a specification.

- Our invention relates particularly to 'a me 'tallic car underframe, and has for its object to provide a strong, rigid, and durable structure adapted to reinforce the floor and sldes of the carbody and thereby increase its resistance to shocks from collision or derailment.

It consists in features of novelty as hereinafter described and claimed, reference being 4had to the accompanying drawingforming part of this specification, whereon,

Figure 1, is a horizontal section through the corner posts of the car-body on l1ne 1, 1. in Fig. 2, showing our improved underlrame in top plan view; F ig. 2, a slde elevation of the underframe and combined partsy of the car-body, broken away; Fig. 3, a vertical transverse section to enlarged scale through the underframe o'n line 3, 3, in Fig. 1 Fig. 4, a horizontal section through-the same on line 4, 4, in Fig. 2, and Fig. 5, a similaryiew to Fig. 3, through the underfranie on line 5. 5, in Fig. 1. Y

Like letters and numerals of reference denote like parts in all the iigures.

Our improved metallic car undertrame (broken away and one-half shown to the left oi' the middle' line of the car, in Figs. 1 and 2,) comprises a body-bolster c adjacent to each end of the frame and preferably of the cast steel type integral throughout. Each body-bolster (L in the present case, is shown as a double body-bolster, preferably Lshaped in cross section, having the body center-pl ate 1 and perforated centrally for the king-bolt in the usual well-known manner; but the body-bolster may be single, and of any suitable design and shape in cross section.

sill b in lieu of being continuous, may be made in sections extending respectively, between and beyond the holsters, and fixed thereto in any suitable manner, but We prefer the construction shown. i

The middle longitudinal sill or member b is preferably composed oi a top plate 3, and a bottom plate 4 which bears on the holsters a, and is wider than the topl plate 3, the plates 3 and 4 being connected together at, and adjacent to their corresponding edges on each side ot, and equidistant from the longitudinal center of the underframe by a Z-shaped bar 5, having when assembled, its upper inner flangeriveted to the top plate 3, and its lower outer flange to the bottom plate 4, theweb of the bar 5 being ilush on the outside with the edge ot the top plate 3, whereby a wide base is lformed to the sill b and a double thickness oi" metal provided thereat for securing the sill l) to the top of the bolsters a by the rivets 6. Similarly, between and across the ends of the body-holsters a at each side of the car-body, is a preferably box-shaped longitudinal girder or member c of like construction to the middle longitudinal sill b, and arranged ilatwise in the Aplane of the side of the car-body, exceptinr that the inner and outer plates 3 and 4, oi each side girder c (corresponding respectively to the top and bottom plates 3, and 4, of thel middle sill b) are of equal Width, the inner plate 3 when assembled, extending upward beyond the outer plate 4, and the outer plate 4 extending downward-beyond the inner plate 3'., Whereby the end and adjacent top portion of each bolster a sets in the inner angle formed at the bottom of the girder c and is iixed to the outer plate 4- thereat by the rivets 6 through a double thickness of metal.

Each girder c preferably extendsupward as far as the wood belt-rail 7 which sets in the outer angle formed at the top of the girder c, the latter being substituted for the ordinary wood sheathing and other railsand Arranged longitudinally across and bepaneling betweenv the belt-rail 7 and sidesill of the underframe. Each gil-'der c is preferably strengthened on the inside by angle irons 8 which are iixed vertically by rivets 9 to the Aplates 3 and 4 alternately as shown..

On the bolsters o. between the middle sill b and side girders c are 'arranged the auxiliary woodlonoitudinal sills 10' on which the Hooring (not shown) is fixed in the ordinary manner, the sills 10 butting endwiseagamst .the end cross sills 1 1 between the corner posts 12 of the car-body, which pass between the inner and outer lates 3 4 of the side girders c to which t ey are fixed ,by angles 13, or in any other suitable manner.

d represents one of the needle -beams, which are composed preferably of cast steel,

-Ishaped in cross sectlon and fixed at the top and ends respectively to the middle sill b and side girders c b f rivets 14 14 in the same manner as the ody-bolsters a, the needlebeams d being made sufiiciently ri id for enabling the queen-posts and truss-ro s ordinarily used to be dispensed with. But if desired queen-posts 15 may be cast (or fixed) on the needle-beams d for the truss-rods 16 as indicated by-full lines in Fig. 2 and by dotted lines in Fig. 5.

By our invention as above described, in

which a metallic middle longitudinal sill having a broad base and rigid Z-sha ed side members extending the entire length of the car between the platform buffer-beams, combined with similarly constructed metallic `side girders forming a considerable portion of the car-body, and rigidly fixed therewith to the body-holsters and needle-beams a very strong structure is produced adapted to resist to the utmost lateral and vertical fiexure and telescoping in case of collision or derailment.

It is here noted that we do not limit ourselves to the use of the Z-sha ed bars 5. for

connecting the plates 3, 4, an 3,'4, respectively, to lfether, as the said plates may be analogous y united by bending and Hanging,

or in any other suitable manner for forming a shallow rectangular box-shaped' structure. What we claim as our invention and desire tosecure by Letters Patent is :e

. 1. A car underframe of the class described, comprising two body-bolsters, a middle longitudinal sill consisting of a shallow rectangular box-shaped girder extending the entire length of and beyond the l car-body, and adapted to be fixed fiatwise to the said bolsters, a buffer-beam xed to each end of the said sill, two opposite side longitudinal members consisting respectively, of 'a rec-l tagular box-shaped girder analogous to the said sill and arranged fiatwise in the plane of the side of the said body, the'said member being adapted to be fixed to the ends 'of the said holsters and to engage the belt-rail of the said body, substantially as described.

2. A car underframe of the class described, l com rising two body-holsters, a middle 1onv gitu 'nal sill consistin of a shallow rectangular box-shaped ir er extendi the entire len th of and eyond the carody, the

thereat to the sald holsters, a buffer-beam fixed to each end of. the said sill, two` opposite side longitudinal members consisti res ectively, of a rectangular box-shapg 'said sil having lateral outward bottom Y 'flanges and adapted to be fixed fiatwise ir er analo ous to the said sill and arranged atwise in t e plane 'of the side of the said' and two opposite Z-shap'ed bars adapted toconnect the said plates together at and adjacent to their corresponding' side edges,the said lates and bars extending the entire lengtli) of thesill, substantially as described.

.4. In a car underframe of the class described, the combination with the bodyholsters, of a shallow rectangular box-shaped sill adapted to be fixed fiatwise'on the said holsters andconsisting of a top late, and a bottom plate of greater width tiian the top late, the said lates extending the entire ength of the sili and the longitudinal edge portions of the top plate being adapted to form a Z-shape wlth the body of sald plate and fixed thereat to the corres onding edge portions of the bottom plate, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
